publicfile consists of an http server
and an ftp server. It was written by D. J.
Bernstein. Like most of his programs, publicfile is trying to be more
secure than many other programs.
Also, like most of his programs, it could be called a little eccentric in
that it behaves a lot different than other programs do. It is certainly
not a simple drop-in replacement for any other http- or ftp-server.
That's why people have written patches for it (listed
here), and that's also why we have
written these patches:
- publicfile-0.52-gzip-1.patch
- This patch enables "Content-Encoding" (gzip). It works as follows:
when a client requests <host>/<file> (via http),
and the request contains a header "Accept-Encoding" whose
value contains the string "gzip",
and if the file <host>/<file> is retrievable,
and if the file <host>/<file>.gz is retrievable,
and if <host>/<file>.gz is not older than <host>/<file>,
then the header line "Content-Encoding: gzip" is added to the response,
and <host>/<file>.gz is returned instead.
In other words, if there is a compressed copy of the file available, it
is returned instead of the uncompressed version, saving some bandwidth.
Update: integrated change by Robert Thille to suppress error message if
<file>.gz doesn't exist
- publicfile-0.52-http10keepalive.patch
- Some (more or less) popular browsers like Netscape-4.x use HTTP/1.0
requests per default. publicfile doesn't support persistent connections
for HTTP/1.0 requests, which can mean a big performance hit for these
browsers (and for the server as well). This patch
enables persistent connections for HTTP/1.0 requests as described in
RFC 2616 section
19.6.2.
There are some known problems with older proxy servers. Read
the RFC before you apply this patch!
- publicfile-0.52-commonlog-2.patch
- publicfile writes log information in a format completely different from
that of other webservers like apache. This makes it difficult to evaluate
the logs using standard tools that expect the files to be in "common
logfile format". This patch makes publicfile's httpd write additional
log lines in common or combined format. A perl script is included to
separate those lines from the original publicfile output.
Update: slight change to make it applyable with the new gzip-1 patch
These patches have been tested together with Giles Lean's "redirect-slash-patch"
and Uwe Ohse's "file types" patch. If you want to use all of these, apply them
in the following order to the unmodified sources:
- http://www.publicfile.org/redirect-slash-patch
- http://www.ohse.de/uwe/patches/publicfile-0.52-filetype-diff
- publicfile-0.52-gzip-1.patch
- publicfile-0.52-http10keepalive.patch
- publicfile-0.52-commonlog-2.patch
The commonlog-patch will need some
modifications to include the userid if you use Jay Soffian's BasicAuth patch.
